2': Claims. (01. 223-15) My invention pertains'to features of noveltyand advantage in machines for applying wrappers around bodies, butrelates more particularly, yet not exclusively, to mechanisms of thischaracter for folding or wrapping the gauze around the absorbent bodiesof sanitary pads and the like.

The leading object or prime purpose of the invention is the provision ofa machine of this type capable of satisfactorily performing the re- 19quired work, which is simple in structure, which is composed ofcomparatively few parts, which operates with accuracy and precision,which is effective and eificient in the performance of its functions,which is unlikely to become deranged or injured in ordinary service, andwhich can be manufactured at relatively small cost.

In the accompanying drawings, forming a part of this specification, andthroughout'the several views of which like reference characters havebeen used to designate the same parts, a present desirable and preferredembodiment of the invention has been illustrated in detail and thesedrawings should be considered in connection with the following detaileddescription of the construction and its mode of operation.

Figures 18, 19 and 20 are vertical cross-sections on lines 18-18, 19-19and 20-20 respectively of Figure 17.

Referring to these drawings, it will be perceived that the machineincludes a main frame 31, the details of construction of which are quiteimmaterialso long as the framework performs its usual supportingfunctions.

At the entrance end of the machine, an endless belt conveyor 32 passingaround a drum 33 feeds or advances the continuous pad strip 34 to themachine, this strip being of light, cottony, fluffy wood-pulp materialor similar absorbent material.

A sheet-metal shelf or support 35 is mounted on the cross-bar 36 andcovers the space between the conveyor 32 and such bar for supporting theincoming end of the pad strip 34 all as is clearly shown in Figure 3.

The machine includes a pair of shears of which the stationary element 37is secured to the supporting cross-bar 36 (see Figures 3, 5, 11 and 12)the companion or co-operating, upper, movable, shear blade 38 beingnormally pulled up or elevated by a contractile coil-spring 39 securedthereto and to a portion of the framework (see Figure 12).

The shear-blade 38 is fulcrumed at 41 and such end of the blade has acircular enlargement carrying an outstanding ball or globular extension42 adapted to co-operate with a cam 43 having an oblique cam groove 44,the cam being mounted in any approved manner on the rotary wheel 45.

The upper shear-blade is ordinarily held in elevated or open position asshown in Figure 12, but when the cam 43, during the revolution of thewheel 45 reaches such a position that the ball 42 enters the groove 44,the blade will be depressed 1 10 and out off a section of the pad, allas will be readily understood.

Wheel 45, carrying the cam 43, is mounted on and fixed to a maintransverse drive-shaft 46 rotatable in bearings 47, 47, as shown mostclearly in Figure 5.

Inwardly of the machine beyond the cutters 3'7, 38, the mechanismincludes an endless belt 48 extended around revoluble drums 49 and 51,the upper stretch of such belt constituting a conveyor. for transportingthe cut-oif section of the pad (see Figure 3).

Drum or roller 51 is mounted on a shaft 53 and this is driven by asprocket chain 52 co-operating with a sprocket-wheel on shaft 53 and asprocketwheel on an upper suitably-mounted rotatable cross-shaft 54, thelatter being driven from the drive shaft 46 by a sprocket-chain 55co-acting with sprocket-wheels on the two shafts 46 and 54.

In this way power is transmitted from the shaft 46 through theconnecting means specified to the shaft 53 in order to'actuate theendless conveyor 48 carrying the severed section 50 of the pad.

It is necessary to separate the severed pad sections longitudinally fromone another in order that they may be properly covered and wrapped inthe gauze or cheese-cloth, and in the mechanism presented, the followingspecified co-operating instrumentalities have been provided.

A stationary, slightly-inclined shaft 56 is mounted in or on theframework and longitudinally slidable on this is a member or carriage 57having a pin and slot connection 58 with a lever 59 fulcrumed at 61 onthe framework at its upper.

end.

A link 62 is fulcrumed to the lever 59 at 63 and it is slotted at 60 forthe accommodation of a reduced-diameter portion of the shaft 54 whichsupports that portion of the link, the latter having also an adjustableroller 64 co-operating with the edge of a cam 65 on and rotatable withthe shaft 54, such roller being always maintained in contact andco-active relation with the cam by reason of a cable 66connected to thelever 59 and passing over a sheave 67, the lower end of the cable beingsupplied with a weight 68 as shown in Figure 1.

From this description, it will be readily understood that the rotationof the cam gives the lever 59 a quick forward movement, such lever beingreturned to original position by the'action of the weight operatingthereon through the cable 66.

The pin or bolt 58 forming part of the loose connection between thelever 59 and the member 57 carries a right-angle bracket 71 (Figures 8and 9) fixed to the end of a slide rod 72 reciprocatory in spacedbearings '73 and 74 forming part of the member 5'7, this bracket '71having a guide-pin '76 slidable in an extension 80 depending from thebearing '74.

A nut 75 on one end of rod '72 secures the bracket member '71 theretoandanother nut 77 on the opposite end of the rod limits the movement ofthe latter to the right as the parts are viewed in Figures 8 and 9.

Rod '72 has an enlarged portion and a section of reduced diameter with ashoulder 78 between them bearing against .a latch 79, the aperturedlower end of whichis held against the shoulder 78 by a coilexpansion-spring 81 encircling the part of the rod of reduced diameterand bearing at one end against the member 73and at its other end againstthe latch '79, all as is clearly depicted.

Latch '79 is fulcrumed at 82 and its toe or finger 90 is designed tocome under a cross-bar 83 (Figures 3, 5, 8, 9 and 10) verticallyslidable in opposite grooves 84, 84 in a bearing 85 upstanding from themember 5'7, such bar 83 being fitted in the upper end of a shaft 86slidable in the opening 87 of the bearing 85 and spring-pulled down--The depending part or tail 93 of this bell.

crank lever, during its reciprocation, co-operates with a fixed cam orabutment 95 shown in Figure '7, such tail riding idly over such abutmentwhen it travels to the left, but rocking the bell-crank lever upwardlywhen it travels to the right, the part 92 of such lever then elevatingthe bar 83 so that the catch '79-90 may rock under its to hold it inraised or elevated position.

In order tohold the member 57 and the parts associated therewith inproper position and against dislodgment until it is intended to move,the machine includes a leaf-spring 96 equipped with a bevelled dog 9'7at its end which co-acts with a companion bevelled projection 98 on thecasting 5'7.

When the lever 59 swings to the left as the parts are seen in Figure '7,the rod '72 will be moved in the same direction sliding in the bearings'73 and 74 until the bracket 71 strikes the end of the bearing 74 andafter that the member 57 is carried along with the bracket.

During the initial movement of the bracket, that is to say, before thecarriage 5'7 moves, the latter being restrained by the action of thecatch 97, the dog 79 is released permitting the bar 83 to descend underthe action of spring 88 and as soon as such descent is accomplished, thewhole carriage and bar are slid along with the bracket 71 pressingagainst the end of bearing '74.

Thus it will be seen that during the first part of the movement of thebracket 71, the catch is released and thereafter the lowered bar ispushed along to feed the severed pad much more rapidly than the travelof conveyor 48.

That is to say, after the section of the pad has been cut ofi from thesupply by the shears 37 and 38, and such severed part has been fedforwardly somewhat as shown in Figure 3, the bar 83 descends back of itand then feeds the cut-off section very rapidly forwardly to secure theproper space between that section and the next one which will be severedfrom the supply.

The strip of gauze or cheese-cloth 101 from the suitably supportedsupply roll or spool 102, and of substantially greater width than thestrip of padding 34, as it leaves the roll 102 passes aroundguide-rollers 103 and 104 up on to the top of an endless conveyor 105extending around drums or pulleys 106 and 107, the shaft of the formerbeing driven from an upper shaft 109 by a sprocket-chain 108 andassociated sprocketwheels on the twoshafts.

Shaft 109 in turn, is rotated from an upper 'crossshaft 112 by asprocket-chain 111 and correlated sprocket-wheels on the two shafts.

A sprocket-chain 113 and companion sprocketwheels on the two shafts 112and 54 transmit the power from the latter to the former so that therotation of shaft 54 through the connecting means specified is carriedto the drum 106 and the endless conveyor belt 105 on which the strip ofgauze rests.

Shaft 112, as is more clearly shown in Figures 3 and 6, has a cam 114 onits end operating in a recess in the side-of an upright shaft 115arranged to slide substantially vertically in suitable bearings, thedetails of which need not be explained.

The lower end of shaft 115 carries a yoke or framework 116 which has apair of upstanding guide-rods 117, 117 (Figure 6) slidable in holes in abracket 118 fastened to the frame so as to hold the yoke 116 in properangular relation during its up and down movements.

The frame or yoke 116 supplies bearings for the-shafts of two rollers,119 and 121, around which extends an endless metal or other belt 122preferably provided on its outerface with small teeth or projections.

The shaft of drum or pulley 119 is driven by a sprocket-chain 123 'andco-operating sprocketwheels on the shaft of such drum and on a shaft 124revoluble in suitable bearings and driven from shaft 109 by gearing 125shown in Figure 6.

Another sprocket-chain 126 co-acting with sprocket-wheels on the shaftsof the two drums 119 and 121 drives the element 121 from the shaft ofthe member 119 so that a very positive action of the two drums issecured as well as of the end less conveyor actuated thereby.

When the severed section of the pad is advanced by the movement of the'bar 83, it is pushed forwardly on top of three parallel rods 131, 131,beneath the conveyor 122 and above the flat strip of gauze 101 on theconveyor 105.

The front ends of the rods are mounted on and supported by a cross-bar132a (Figures 3 and 6) carried on the upper ends of two supporting andguide rods 132, 132 slidable in apertures in the spaced flanges 134 and135 of a channel bar 130, the lower ends of the two rods, 132, 132 beingconnected together by a cross-bar 133 which also acts as a stop to limitthe upward travel of the parallel'rods 131 by coming into contact withthe underside of the bar 129 on which the channel bar 130 is mounted.

The supporting bar 132d is pushed upwardly by an expansion coil spring136 bearing on the flange 135 at its lower end and pressing at its otherend on a rod or plunger 137 secured to the part 1321;

and extending downwardly through a hole in the flange 134.

It will be understood, therefore, that the supporting rod's- 131 aremaintained in the position shown in Figure 3 by the action of spring 136but that they are susceptible of being pushed down, under whichcircumstances the rods 132 would slide in their bearings and the spring136 would be somewhat compressed.

To effect such descent of the bars or rods 131, the member 116 issupplied with a bent finger 138 (Figure 3) adapted during the descent ofthe conveyor 122 to engagethe bar 132a and press the bars 131 down so asto permit contact between the pad carried by them and the layer of gauzebeneath them so that thereafter the two may travel together, it beingunderstood that the speed of the two conveyors 105 and 122 isapproximately the same. The continuous strip of gauze and the spacedpads thereon upon leaving the conveyor 105 pass on to the top of anotherendlessconveyor 139 The outer surface of the endless conveyor 139 8 0'may have slight projections or points thereon if desired to secure firmcontact and pulling action on the strip of gauze resting thereon.

This conveyor travels through the lower portion of a sheet-metal foldercharacterized as a whole 144 and which has deflecting side wings 145 and146 which fold up the protruding side portions of the gauze and wrapthem over on to the top face of the pad one on top of the other as shownin Figures 18,19 and 20 in which the one side wing or section of thegauze has been characterized 147 and the opposite part denominated 148.

Itwill' be understood, therefore, that as the product leaves theconveyor 139, the gauze will be folded over upon itself and at certaindistances apart, sections of the pad will be within such folded fabric.

It now becomes necessary to sever the fabric between such pads and tofold the front and rear end portions of the gauze over on to the body ofthe pad and then discharge the finished product from the machine.

This severing and folding operation occurs on a wheel construction nearthe discharge end of 165 the appliance and that portion of the mechanismwill now be described. a

A suitably journaled cross-shaft 151 is rotated by means of asprocket-chain 152 co-operating with sprocket-wheel 153 on such shaft anidler sprocket-wheel 154 and a sprocket-wheel 155 on the drive-shaft 46heretofore mentioned.

Mounted fixedly on shaft 151 so as to revolve therewith, I provide awheel 156 having outwardly-fiaring side-walls 157, 157around itsperiphery 31115 and between which the wheel has three recesses orcavities adapted to receive the pad-equipped portions of thelongitudinally-folded gauze.

The bottom wall 158 of each such pocket comprises a plate mounted onthetop of a rod or 125) shaft 159 slidable radially in a bearing 161 andnormally pulled inwardly to the bottom of the cavity by a pair of coilcontractile springs 162, 162.

In order to keep the plate always in proper 125 register with thecavity, it is supplied with a sliding guide-pin 163 extended through ahole in the bottom of the pocket.

This plate or wall 153 constitutes the slidable discharge means fordelivering the finished prod- 2 not and the means for, actuating it willbe described hereinafter.

At one end of each such pocket or socket on the wheel there is a shorterwall 164 provided with a plurality of outstanding pins 165 and hinged 35at 166 there is a sheet-metal folder apertured to receive the pins, thesharp points of which project through the folder holes into the strip ofgauze 101.

Shaft 166, to which the folder 167 is fastened, is equipped with atorsional spring 163 (see Figwe 16) tending to rock the folder over ontop of thepad in the adjacent pocket and the other end of shaft 166 hasa dog 169 of the curved form shown in Figure 13, the dog specifiedriding on the inner surface of a stationary, mutilated, circumferentialrim 171-which is omitted on the left-hand portion of the appliance asshown on the corresponding pa of Figure 13, one end of such rim havingsecured thereto a. bent guide 172 to assist in turning the dog back intoposition after the folder has swung over in response to the action ofspring 168.

At the other end of each pocket or cavity, there is another wall 1'13 atan angle thereto and equipped with the pin points 165 to engage thegauze or fabric.

On a shaft 174 a similar perforated or apertured folder 175 is secured,its perforations or holes being for the same purpose of permitting thesharp pins to project through to engage the fabric on the outside of thefolder.

Each such shaft 174 (Figure 15) is similarly equipped with a torsionalspring 176 tending to rock the folder over on top of the pad in thepocket or recess and in like manner the opposite end of the shaft 1'74is supplied with a curved dog 178 which co-acts with what might be aptlytermed a stationary cam 179 which is cut away or omitted for a portionof the circle as shown in the left-hand part of Figure 13 to permit thefolder to turn by freeing the dog from the holding action of the cam.

Of course the pads are so spaced in the wrapped or folded gauze thatthey will register accurately with the three pockets or sockets of thiswheel as the fabric and such interfolded pads are wound on the wheel bythe rotation of the latter.

To assist in applying the pad-equipped, lengthwise-folded gauze to thewheel on which it is wound as specified, a roller 181 presses on the topface thereof to assure its positive application to the projecting pins165, the rotation of which, with the wheel, pulls the continuous stripalong and winds it on the wheel.

Such roller is mounted on the lower end of a rock-arm 182 which may beweighted, if desired,

to more efficiently perform its work.

The wheel, adjacent to each of its sections 164, carries a pair ofshears 183, 184, similar to the shears 37, 38, already described, andwhen the ball or rounded end 185 of each such set of cutters coacts witha stationary grooved cam 186 (Figure 14), the shears close and cut thelongitudinally-folded gauze between the pads, thus di'-'- viding thegauze'into individualsections ready for folding over on to the top ofthe encased pad.

The cam is so positioned that the part of the gauze behind the shearswill have become applied to the pin points before the severing occurs,so that the oncoming continuous strip of gauze will be drawn on to thewheel in a manner well understood.

The severing having taken place, then the folders work to fold over thefront and rear sections of gauzeon to the top of the pad by 'themechanism' already referred to.

When the pad reaches the lower part'of the wheel duringthe revolution ofthe latter, its ejector plate 158 is operated to discharge thecompletely-wrapped pad 187 on to an endless delivery conveyor 188.

To accomplish this result, each rod 159laears on an arm 189 which restson a stop-pin 191', each such arm being fixedly mounted on a rock-shaft192 oscillatory in a bearing 193 of the wheel and having a finger 194.on its protruding end to coact with a stationary roller 195 againstwhich it is projected by the springs 162 previously mentioned (seeSigures 4, 13, 14, and 15).

This roller is so positioned that the ejector plate will be in normalinoperative position dur ing the gauze-folding action and will move todischarge the completed product on to the'conveyor terial, means tosever said pad material strip into From the preceding, it will beunderstood that the pad and gauze materials are supplied to the machineuninterruptedly in continuous supply strips, that the pad strip issevered into separate pads which are longitudinally spaced apart andapplied in that relation to the continuous gauze, that the latter isthen folded longitudinally over the side edges of the pads, that thegauze between the pads is cut, that the front and rear parts of thegauze are folded endwise over on to each pad, and that the finishedproduct is delivered from the machine, all-of these operations takingplace wholly automatically.

An important feature of the invention resides in the fact that thefolders 16'? and 175 are perforated, this construction greatlyfacilitating the folding action as due to the perforations, the airpasses through the folding blade during the folding action, and therebyholds the gauze in'place thereon. The greater the speed of operation ofthe folding blades, the greater is this effect. If

the blades were not perforated, the gauze would .tend to shift from offthe blade with the result that an uneven fold would be produced.

The invention is susceptible of a variety of embodiments and istherefore not limited to the precise and exact mechanical detailspresented because these may be modified within comparatively wide limitswithout departure from the heart and essence of the invention as definedby the appended claims and without the sacrifice of any of the materialor substantial benefits or advantages of the invention.
